Hardware connection table. This is the sample program to read and write RFid data using RC522 on Raspberry Pi. Before that, please install RC522 python3 library. import RPi. GPIO as GPIO Thanks for reading this tutorial.
Can you read and write a RFID tag?
Now you can read and write your own RFid tag/card. I have publish a tutorial regarding this topic before, around 2018. But now the library seems not compatible. So I decided to create a new tutorial and add a write function.
